The Texas Instruments LM5175 is a versatile 4-switch synchronous buck-boost controller designed for step-up/step-down DC/DC conversion. It supports a wide input voltage range from 3.5 V to 42 V, with a maximum rating of 60 V. The flexible output voltage can be set from 0.8 V to 55 V.
Key electrical features include an adjustable current limit, frequency synchronization, power good indication, prebias startup, and adjustable UVLO. The controller also incorporates synchronous rectification for high efficiency and features frequency dithering and spread spectrum for EMI reduction. The typical quiescent current is 1.65 mA.
Available in VQFN-28 and HTSSOP-28 packages, the LM5175 is suitable for surface mount applications. Its operating temperature range is -40°C to 125°C. The device provides features like VOUT short protection, high efficiency buck-boost transition, and selectable CCM or DCM operation with pulse skipping.
This controller is ideal for applications requiring efficient and flexible voltage regulation across a broad range of input and output conditions.
